DEVICE FOR LOGATING AND RAISING SUN KEN' VESSELS.

To all whom t may concern:

' Be it known that I, FREDERICK B. Lotions, a citizen of the UnitedStates, and a resident of the city of Chicago, county of Cook, and Stateof Illinois, have invented certain new and useful Improvements inDevices for Locating and Raising Sunken Vessels, of which the followingis a specification.

My invention relates to improvements in devices for locating and raisingsunken vessels and has for its object the provision of a device of thischaracter which shall be of simple construction and eiiicient in'operation.

The device consists in the combination and arrangements of partshereinafter described and claimed.

My invention will be best understood by reference to the accompanyingdrawing which is an elevation partially in section illustrating a deviceembodying my invention in operative position for locating and raising asunken vessel.

The preferred form of construction as illustrated in the drawingcomprises two cylindrical casings l secured to the upper deck of avessel 2 as shown. A securing member 3 is bolted to the keelson of thevessel and projects upwardly into the bottom portion of each of thecasings l, the said securing member being provided with a securing eye4L at its upper end. A heavy cable 5 has one end connected tio thecorresponding eye 4: by means of a swivel connection 6, the said heavycablebeing coiled in the corresponding casing as indicated. The otherend of cable 5 has a double swivel connection 7 with one end of alighter cable 8 as indicated. Cable 8 is normally coiled in thecorresponding casing above the corresponding heavy cable and its otherend is connected by means of a swivel connection 9 with the bottom of afloat 10 as indicated. The upper edge of each of the casings l isprovided with a supporting and sealing Speeication of Letters Patent.

lip l1 and each of the floats 10 is provided with an annular supportingand sealing recess 12 adapted to receive said lip.

In use the cables 5 and 8 are coiled in the corresponding casing l andthe corresponding lfloat seated on said casing with the lip 1l restingin recess 12 thus forming avvaterproof sealing for the exclusion of iwater from said casing.

In case the vessel should sink the floats 10 will readily rise from thecasings l and ride upon the surface of the water being held `to saidship by means of the lighter cables 8. Upon discovery of floats 10 thelighter cables 8 may be employed for raising the heavy cables 5 by meansof which the vessel itself may be raised to 4the surface of the water. i

Having described my invention what I claim as new and desire to secureby Letters Patent is:

The combination with a vessel, of a casing secured to the deck thereof;a float having a larger part resting on the top of said casing and asmaller part extending into and fitting the bore of said casing andforming` a liquid tight joint between the top portion of said casing andsuch float; a swivel secured to the lower end of such float; a smallcable having one end secured to the end of said swivel; a second swivelsecured to the other end of said small cable; a second and larger cablehaving one end secured to said second swivel; a third swivel secured tothe other end of said larger cable; and a member rigidly secured totheframe of the vessel and secured to said third swivel, substantially asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
